ERNEST R. WOLFE, OF KUSHEQUA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO T. E. MOULTON, OF SAME PLACE.

LOCK FOR DOG ATTACHMENTS OF LOGGING-CARS.

SPECIFICATION forming part of Letters Patent N o. 601,419, dated March 29, 1898. Application filed December 29, 1897. Serial No. 664,269. (No model.)

To all whom t may con/cern.-

Beit known that I, ERNEST R. WOLFE, a citizen of the United States, residing at Kushequa, in the county of McKean and State of Pennsylvania, have invented a new and useful Lock for Dog Attachments of Logging- Cars, of which the following is a specification. i

The invention relates tol improvements in locks for standards or dog attachments of logging-cars.

The object of the present invention is to improve the construction of locks for standards or dog attachments of logging-cars and to provide a simple, inexpensive, and efficient device capable Vof locking a pair of dogs or standards in their engaging position and of releasing either one without aecting 4the other to enablevlogs to be discharged at either side.

The invention consists in the construction v and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended. In the drawings, Figure l is a perspective view of a portion of a car provided with a locking device constructed in accordance with this invention, both standards or dogs being in their engaging position. Fig. 2 is an elevation, one of lthe dogs being released.

Like numerals of reference designate corresponding parts in both figures of the drawings. f

l 1 designate a pair of dogs or standards pivoted between their ends on bolts 2 on the end of a car Sat opposite sides thereof and adapted, as illustrated in the accompanying drawings, to project above thel car and prevent logs from rolling off the same. The dogs are adapted to be mounted on any construction of logging-car and may be used on a logging-sled but they are especially adapted for the car 3, which is provided with rails and adapted to be loaded by steam. The standards or dogs, which are disposed at a slight outward inclination, have their upper ends rounded at the inner edges, and -their lower ends engage fixed stops 4, mounted on the car at the outer edges of the dogs or standards and limiting the inward swing of the upper portions of the same. The 'outward swing of the upper portion of the dogs or standards is limited by upper xed `stops 5, mounted on the car, at the outer edges of the said dogs or standards adjacent to the pivots 2.

The dogs or standards are locked in" an up'-v` right or engaging position by a transverse rock-shaft 6, journaled on the car in suitable bearings 7 at the lower ends ofthe said dogs or standards and provided with lugs or shoulders 8, arranged to engage the same and adapted when the rock-shaft is partially rotated to be carried 'out of such engagement to release one of the dogs or standards and permit the same to be depressed, as illustrated in Fig. 2 of the accompanying drawings, in order that logs may be discharged from that siderof the car. l When the lugs are in a vertical position, they engage the dogs or standards, and they are retained in that position by a substantially L-shaped spring 9, secured at one endto the car and having its other arm bearing against one of the lugs or shoulders.` The spring is also adapted to retain the rock-shaft out of engagement, and the said rock-shaft has its ends bent at an angle to form handles l0, by means of which it may be readily operated.

In order to retain one of the dogs or standards in its engaging position when the lugs or shoulders of the rock-shaft are swung downward, a fastening device 1l is employed and is adapted to be arranged in either one of a pair of openings or sockets 12, which are located at the inner edges of the dogs or standards near the lower ends thereof. This fastening device may be readily transferred from one side of the car to the other, so that either one of the dogs or standards may be released, While the other is retained in its engaging position.

It will be clear that the invention possesses the following advantages The locking mechanism is simple and comparatively inexpensive in construction, it is positive and reliable in its operation, and it may be readily mounted upon a logging car or sled. It is adapted to release a dog or standard at one side of the car and retain the one at the opposite side in its engaging position, andthe removable fastening device,which is adapted IOO i to be arranged at either side of the car, will enable either one of the dogs or standards to be released.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

l. In a device of the class described, the

combination with a car, of .a pair of pivotallymounted dogs or standards located at opposite sides of the'car and projecting above the same to retain logs thereon, anda rock-shaft journaled on the car in suitable bearings and provided with lugs or shoulders engaging the lower ends of the dogs or standards and locking them in their engaging position, said rockshaft'being adapted to be rotated to carry the lugs or shoulders away from the dogs or standards'for releasing the same, substantially as ,described 2. In a device of the class described, the combination with a car, of a pair of pivotallymounted dogs or standards located at opposite sides of the car and projecting above the same to retain logs thereon, a rock-shaft journaled on the carin suitable bearings and provided with lugs or shoulders engaging the lower ends of the dogs or standards and locking them in their engaging position, said rockshaft being adapted to be rotated to carry the lugs or shoulders away from the dogs or standards for releasing the same, and a removable fastening device mounted on .the car and engaging one of the dogs or standards and locking the same when the rock-shaft is swung downward,said fastening device being adapted to be arranged at either side of the car to lock either of the dogs or standards, substantially as described.

3. In a device of the class described, the combination with a car, of a pair of dogs or standards pivotally mounted thereon at opposite sides thereof, the upper and lower stops arranged at lthe outer edges of the dogs or standards, a horizontal rock-shaft provided with lugs or shoulders engaging the inner edges of the lower end of the dogs or standards, and a spring mounted on the car and bearing against the rock-shaft, whereby the lugs are retained in engagement with the dogs or standards, substantially as described.

4;. In a device of the class described, the combination with a car, of a pair of dogs or standardspivotally mounted thereon at opposite sides thereof, a rock-shaft provided with lugs or shoulders engaging the dogs or standards at the inner edges thereof, the upper and lower stops mounted on the car and located at the outer edges of the dogs or standards, a spring mounted on the car and engaging oneJ of the lugs, and a fastening device for locking one of the dogs or standards against movement when the lugs are carried away from the same, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
